F(x) = x+2
g(x) = 3x

workout the value of gf(5)

g(5) = 15 and f(5) = 7

Step-by-step explanation:

f(5) = x + 2

f(5) = 5 + 2

f(5) = 7

g(5) = 3x

g(5) = 3(5)

g(5) = 15

plz mark as brainliest if correct!!!

21

Step-by-step explanation:

because firstly u substitute 5 into x in the f equation

so it will be f(x)=5+2=7

the substitute 7 into the g equation

so g(x)= 3 x 7= 21

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
